Methods: Through the Genetic Resolution and Assessments Solving Phenotypes in LGMD (GRASP-LGMD) Consortium, 42 subjects with LGMDR1 were enrolled in a 12-month natural history study across 11 international sites. Each subject completed a battery of clinical outcome assessments (COA), including the North Star Assessment for Limb Girdle-Type Dystrophies (NSAD), 10-m walk/run, and Performance of the Upper Limb (PUL), in addition to several patient-reported outcome measures (PROM). Results: In this baseline cross-sectional analysis, significant correlations were found between COAs and PROMs, with significant differences in the performance of assessments based on subjects' ambulatory status and genetic variant classification. Interpretation: The study has determined that the NSAD and other assessments are valid and reliable measures for quantifying the level of disease impairment in individuals with LGMDR1.
